here they are, same basic design as the others. these were built for more of my friend and are the last i will build before finishing my prop injected one. i would love to build more but i am moving to Okinawa japan in a few days. i wonder if they have anywhere to buy supply's there?

its already been done. http://www.thehomegunsmith.com i built one of those (quite a bit more involved then a spud gun but still fun). i cant post pictures for obvious reasons but there are a few on the website.
